According to the legend, Hanuman the Monkey God had been sent by Rama to the Himalayas to find a particular medical herb to rescue Sita from the demon king Ravana. When Hanuman arrived at the Himalayas he had forgotten which herb he was looking for and he had decided to bring a chunk of the Himalayas back in his jaw, hoping that particular herb was growing on it. Legend says that Hakgala Mountain was formed by the chunk of rock brought from the Himalayas by Hanuman.
